Worksheet: Grouped Frequency Tables
In this worksheet, we will practice reading and interpreting frequency tables and tally charts and forming a frequency table for a given quantitative data set.
The table of numbers shows the marks of 30 students in a mathematics exam.
Using this data, complete the frequency table.
- A4, 7, 4, 3, 5
- B5, 8, 5, 6, 6
- C6, 8, 7, 4, 5
- D6, 9, 8, 7, 6
- E3, 7, 5, 8, 7
The table of data shows the heights in centimeters of teachers at a school. Using a frequency table, find the number of teachers who are 175 cm or more.
The table shows the weekly wages of 30 workers in a factory. By forming the frequency table using the intervals 30–39, 40–49, 50–59, 60–69, 70–79, 80–89, and 90–99, find which interval has the highest frequency.
The table shows the marks of 100 students in a recent science exam. What percentage of students received 20 marks or more?
Given an interval with lower limit 16 and center 23, find the upper limit of the interval.
The table shows donations made by students to a charity. How many students donated between 60–70 pounds?
|Donation in Pounds||20–29||30–39||40–49||50–59||60–69||70–||Total Number of Students|
|Number of Students||4||2||3||7||16||5||37|
The table shows the distribution of exam marks in science for 1 000 students. By drawing a cumulative frequency curve, determine the number of students who scored 54 marks or more.
- A637 students
- B585 students
- C631 students
- D124 students
- E507 students
The table shows the bonuses received by 75 factory workers. How many workers received a bonus which was less than 50 LE?
|Number of Workers||10||5||10||15||25||10||75|
The scores that 30 students achieved in a maths exam are shown in the table. By constructing a frequency table of the scores, with groups 20–23, 24–27, 28–31, 32–35, and 36–39, find the group with the lowest frequency.
The table shows the marks of 100 students in a recent mathematics exam. What percentage of students received 30 marks or more?
